Spy vs. Spy is a wordless comic strip published in Mad magazine. It features two agents involved in stereotypical and comical espionage activities. One is dressed in white and the other in black, but they are otherwise identical and are particularly known for their long and beak-like heads and their white pupils and black sclera. The duo are always at war with each other, using a variety of booby traps to inflict harm on the other. The spies usually alternate between victory and defeat with each new strip.
